Benefits of technology

This design enhances the friction force transmission, reduces the loading on the support belt, and increases the maximum supportable force without causing damage, providing a durable and cost-effective belt end connection that can withstand elevated temperatures.

Problems solved by technology

If the elevator installation also has to withstand a fire situation in the building, the belt end connection also has to endure increased temperatures.
A disadvantage of this construction is that the support belt is subjected in the regions of increased pressing to a very strong punctiform loading, which can have a disadvantageous effect on the service life of the support belt.

Embodiment Construction

[0029]The following detailed description and appended drawings describe and illustrate various exemplary embodiments of the invention. The description and drawings serve to enable one skilled in the art to make and use the invention, and are not intended to limit the scope of the invention in any manner. In respect of the methods disclosed, the steps presented are exemplary in nature, and thus, the order of the steps is not necessary or critical.

[0030]The elevator installation 1 consists, as illustrated in FIGS. 1 and 2, of a car 3 and a counterweight 4, which are moved in opposite sense in an elevator shaft 2. The car 3 and the counterweight 4 are connected together and supported by means of a support belt 6. One end of the support belt 6 is fastened by a belt end connection 9 to the car 3 or the counterweight 4, according to FIG. 2, or in the elevator shaft 2, according to FIG. 1. The location of the fastening is oriented towards the mode of construction of the elevator installati...

Abstract

A belt end connection and method for fastening a belt end in an elevator installation includes a housing having a wedge pocket for holding the support belt end and a wedge. At least one wedge pocket surface facing the wedge is provided with a roughness that is different from a roughness of another surface of the wedge pocket. Advantageously, a wedge pocket adhesion surface lying closer to a loose run of the support belt is provided with a roughness greater than the roughness of the another surface, or a wedge pocket slide surface lying closer to a supporting run of the support belt is provided with a roughness less than the roughness of the another surface.

Description

FIELD OF THE INVENTION[0001]This invention relates to a belt end connection for fastening an end of a support belt in an elevator installation and a method for fastening an end of a support belt in an elevator installation.BACKGROUND OF THE INVENTION[0002]An elevator installation usually consists of a car and a counterweight, which are moved in opposite sense in an elevator shaft. The car and the counterweight are connected together and supported by means of a support belt.[0003]One end of the support belt is in that case fastened by a belt end connection to the car or the counterweight, respectively, or in the elevator shaft. The location of the fastening is directed towards the form of construction of the elevator installation. The belt end connection accordingly has to transmit the force, which acts in the support belt, to the car or the counterweight, respectively, or to the elevator shaft. It has to be designed in such a way that it can securely transmit a required supporting f...
